How a powerful digital servo works

The digital controller receives a PWM signal from the receiver. The pulse duration sets the target rotation angle. The microcircuit compares it with the current position. When diverging, the motor rotates the metal gears. Double bearings reduce friction and play. The potentiometer constantly reports the actual position of the shaft. The shaft rotates precisely to the desired angle with high frequency.

Technical characteristics and functionality

Model TD-8135MG operates at a voltage of 4.8–7.2 V. The no-load speed is 0.32 s/60° (at 4.8 V). At 7.2V the speed improves to 0.22s/60°. The peak stopping torque at 4.8 V is 32.7 kg cm. At 7.2 V the moment increases to 35.2 kg cm. The quiescent current is 140–200 mA. The stopping current reaches 2600–3400 mA.

The servo drive has 5 metal gears and double bearings. The body is made of PBT engineering plastic and aluminum alloy. The dimensions of the device are 40.0×20.5×40.5 mm. Weight is 56 grams ±5%. Connecting wire length 320 mm ±5 mm.

The pulse width range is 500–2500 µs. The neutral position corresponds to 1500 µs. The rotation angle reaches 180°±3° with a signal of 500–2500 μs. The Dead zone is 5 microseconds. Operating temperature ranges from -25°C to 70°C.
